Dave Gettleman, the general manager of the Giants, announced on Tuesday he has been diagnosed with lymphoma. The 67-year-old said he will continue to handle his responsibilities to the team while receiving treatment.

“The doctor’s outlook for the treatment and the prognosis is positive, and so am I,” Gettleman said in a statement released by the team. “I will continue to work as much as the treatment process will allow, and as they know, when I am not in the office, I will be in constant communication with Pat [Shurmur], Kevin [Abrams] and the rest of our staff.”

That staff includes Abrams, who is the assistant general manager, along with Mark Koncz who was recently hired as the director of player personnel and Ken Sternfeld who serves as director of pro personnel.

Gettleman was hired as GM of the Giants in December shortly after the team fired Jerry Reese from the position. He had spent four years as general manager of the Panthers after serving 15 years in the Giants organization.

Upon his return to the Giants, he immediately went to work rebuilding the roster and the locker room culture. He was the key decision-maker on the hiring of Shurmur as head coach, the signing of offensive tackle Nate Solder and other free agents, and the drafting of running back Saquon Barkley with the second overall pick in April’s draft. He also made the organizational decision to stick with Eli Manning as the team’s starting quarterback entering the 2018 season.

There remain several key decisions on the desk of the general manager in the coming weeks and months, most notably a potential contract extension for wide receiver Odell Beckham Jr. The star player figures to become the highest-paid receiver in the NFL if a deal is struck, but the possibility of a holdout as Beckham enters the final year of his rookie deal hovers over any negotiations.

Gettleman said in the statement that the diagnosis came during an annual physical and the treatment will begin “in the very near future.” The Giants end their offseason training program next week with a three-day mandatory minicamp and then will be mostly dormant until training camp starts in late July.

“I am thankful to John Mara and Steve Tisch and our organization for their support and encouragement, and to Ronnie Barnes (the Giants’ long-time head trainer and senior vice president of medical services) for his guidance and assistance,” Gettleman said in the statement. “And, of course, to my wife Joanne and our children for their love and support. . . . . I look forward to being back at full strength and devoting all my energy to helping make this 2018 New York Giants team the best it can be.”

Giants add punter. The Giants signed first-year punter Taylor Symmank, who was with Shurmur’s Vikings last offseason and preseason but did not make any NFL roster in 2017. He also participated in the Vikings’ 2016 rookie minicamp. Symmank, from Texas Tech, will compete with third-year punter Riley Dixon for the job with the Giants. Dixon was obtained in a trade with Denver on April 23.
